- Updated creds_example.yml

- Added credentials.json -> creds.yml migration
- Migrated credentials.json fields are:
  - Token
  - OwnerIds
  - GoogleApiKey
  - OsuApiKey
  - CleverbotApiKey
  - TotalShards (although you should set this from Coordinator's coord.yml TotalShards, so this setting will usually have no effect)
  - PatreonAccessToken and PatreonCampaignId
  - VotesUrl and VotesToken
  - BotListToken
  - RedisOptions
  - LocationIqApiKey and TimezoneDbApiKey
  - CoinmarketcapApiKey
